A user of mine is connecting via DSL service to our sftp server as part of OpenSSH 3.7.1p2. He claims that he used to be able to upload/download files fine successfully. Now, he can list files, and download files, but he cannot upload files. He says that all uploaded files end up being 0 bytes in size. I asked him to upgrade to the latest OpenSSH 3.7.1p2 because he was using an earlier client. He did this. He reports that now, the session goes like this: [minas@localhost minas]$ sftp cs.yorku.ca Connecting to cs.yorku.ca... minas@cs.yorku.ca's password: sftp> version SFTP protocol version 3 sftp> put cviureview_online Uploading cviureview_online to /cs/home/minas/cviureview_online cviureview_online 0% 0 0.0KB/s --:-- ETA > cviureview_online 0% 0 0.0KB/s --:-- ETA > cviureview_online 0% 0 0.0KB/s> --:-- ETA > cviureview_online 0% 0 0.0KB/s -> stalled ... and hangs. He is running on Linux and the server is running on Solaris, but I have been able to transfer files locally from the Linux box to the Solaris box. It seems like a bug, but I'm not sure what it is or what to recommend to him in order to assist in solving this problem. The user can login via ssh without any problems.
Could be an MTU problem. See: http://www.snailbook.com/faq/mtu-mismatch.auto.html
